Detailed Description

802.11 PHY layer model

This PHY implements a model of 802.11a.

The model implemented here is based on the model described in "Yet Another Network Simulator", (http://cutebugs.net/files/wns2-yans.pdf).

This PHY model depends on a channel loss and delay model as provided by the ns3::PropagationLossModel and ns3::PropagationDelayModel classes, both of which are members of the ns3::YansWifiChannel class.

◆ DoDispose()

void ns3::YansWifiPhy::DoDispose ( void )

protectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.
